Description

Technical Field

[0001] The present invention relates to the technical field of lithium batteries, and in particular to a high-efficiency conveying device for lithium battery helium detection and a working method thereof. Background Art

[0002] With the development of lithium battery technology, the market demand for lithium batteries is growing. However, the safety and reliability of lithium batteries are directly related to the quality of products and the safety of users. Therefore, it is particularly important to conduct strict quality inspections on lithium batteries during the production process. Among them, helium detection, as an effective detection method, is widely used in the sealing detection of lithium batteries.

[0003] In the existing lithium battery helium detection process, the conveying device plays a vital role. However, the traditional conveying device has certain limitations when used. For example, in the Chinese patent with the announcement number "CN211768593U", a high-efficiency conveying device for lithium battery helium detection is disclosed. When the device conveys lithium batteries, in order to ensure orderly transportation of lithium batteries, a guide component is set to separate the lithium batteries, but the position of the structure is fixed and cannot be adjusted. Therefore, although the device can convey lithium batteries, it cannot be adjusted according to the specifications of the lithium batteries, and the use scenario is limited.

[0004] For another example, in a Chinese patent with the publication number "CN 115009795A", a conveyor line for helium inspection of lithium batteries is disclosed. When the lithium batteries need to be inspected by helium inspection, the lithium batteries to be inspected are transferred to the tray on the first conveyor line through the loading mechanism. The first conveyor line transports the tray and the lithium batteries to be inspected toward the helium inspection mechanism. When transported to the helium inspection mechanism, the lithium batteries to be inspected and the tray are transferred as a whole to the helium inspection mechanism by the transport mechanism. The helium inspection mechanism is turned on to perform helium inspection on the lithium batteries. After the helium inspection is completed, the transport mechanism transfers the tray to the first conveyor line and transports it to the next station, thereby realizing continuous inspection and transportation of lithium batteries. In this transport scheme, the components for guiding the lithium batteries are the sorting channel, the first guide plate and the second guide plate. Since the position of the above-mentioned guide structure is also fixed and cannot be adjusted, this transport scheme also has the defect of a narrow scope of application.

[0005] In the above existing conveying technologies, when helium detection is performed on lithium batteries of different specifications, multiple conveying devices or multiple conveying lines need to be arranged to meet the needs, which occupies a large area and has high equipment costs, and has obvious limitations.

[0042] Embodiment 1

[0043] In a typical embodiment of the present application, a high-efficiency conveying device for lithium battery helium detection is provided, such as Figure 1-11 As shown, it includes a conveying component 2 and a partition component 1, and a conveying channel for conveying lithium batteries along a preset path is formed on the conveying component 2, and a plurality of partition components 1 are arranged in parallel above the conveying channel, and the length direction of the partition component 1 is the same as the direction of the conveying channel, and a plurality of sorting channels are formed with intervals between each two adjacent partition components; the feeding end and the discharging end of the conveying channel are provided with connecting rods 12, and the two ends of the partition component 1 are respectively slidably connected to the two connecting rods 12, and the distance between adjacent partition components is changed by sliding the partition component 1 along the connecting rod 12, so that the width of different sorting channels can be adjusted to adapt to different lithium batteries to achieve orderly transportation.

[0044] In this embodiment, Figure 1 , 2As shown, when lithium batteries need to be transported, the partition assembly 1 is pulled to move along the connecting rod to adjust the distance between two adjacent partition assemblies. After the distance between two adjacent partition assemblies is adjusted to the required spacing, the lithium batteries to be transported are placed on the conveying channel, and the lithium batteries are transported through the conveying channel. At the same time, the partition assembly is used to guide the lithium batteries in different sorting channels to achieve orderly and smooth transportation. The device can adjust the width of each sorting channel according to the actual needs of transporting lithium batteries, and can be used in different usage scenarios.

[0045] Specifically, Figure 3-5 As shown, the conveying assembly 2 includes a base frame 21, the top of the base frame 21 is open to form a top groove 22, a plurality of transmission rollers 24 are arranged side by side inside the top groove 22, adjacent transmission rollers 24 are rotatably connected, the outer ring of the transmission roller 24 is provided with a conveyor belt 23, and the top surface of the conveyor belt 23 forms a conveying channel for conveying lithium batteries. A motor 25 is fixedly installed on one side of the base frame 21, and the output end of the motor 25 is connected to one of the transmission rollers 24 to provide power, and the transmission roller drives the conveyor belt to convey along the set direction to convey the lithium batteries.

[0046] Specifically, combined Figure 3 , 4 As shown in , 6, the separation assembly includes a connecting rod 12 arranged at both ends of the conveyor belt, and the two ends of the connecting rod 12 are respectively fixedly connected to the support rod 11, and one end of the support rod 11 is fixedly connected to the base frame 21, so as to realize the fixed connection between the connecting rod and the base frame, and the sorting channel during lithium battery transportation is located between the two connecting rods. Among them, the connecting rod 12 is provided with a slot 13 that passes through from top to bottom along its own length direction.

[0047] Specifically, combined Figure 1 , 6 As shown in Figures 7 and 8, the partition assembly also includes a connecting frame 17 arranged on the connecting rod. A plurality of connecting frames 17 are arranged on the connecting rod 12 at the feed end and the discharge end. A partition plate 14 is fixedly connected between each two corresponding connecting frames 17. The connecting frames 17 and the connecting rod 12 are slidably connected, thereby forming a plurality of partition plates 14 that can slide linearly along the connecting rod 12. There is a certain interval between each two adjacent partition plates 14, thereby dividing the conveying channel into a plurality of sorting channels. Under the guidance of the partition plates 14, the lithium batteries are transported in an orderly manner along each sorting channel. Since the connecting frame is slidably connected to the connecting rod, the distance between the two adjacent partition plates 14 can be adjusted, so that the width of each sorting channel can be changed according to the conveying requirements of the lithium batteries, so that the same specification of lithium batteries can be conveyed, and different specifications of lithium batteries can be conveyed simultaneously using different sorting channels, which greatly improves the applicable scenarios and conveying efficiency of the conveying device and can better meet the conveying requirements in the lithium battery helium detection process.

[0048] Specifically, combined Figure 7, 8 As shown in Figures 11, the bottom of the connecting frame 17 is recessed to form a mounting groove 18 matching the connecting rod 12, and the inner top of the mounting groove 18 is fixedly connected to an insertion rod 19, the lower end of the insertion rod 19 passes through the slot 13 on the connecting rod 12 and can slide relatively along the slot, and a detachable screw ring 110 is screwed on the insertion rod 19, and the spacing between the guide rods can be adjusted according to actual needs; when the connecting frame 17 is connected to the connecting rod through the insertion rod and the slot, the screw ring 110 is located below the connecting rod 12, which plays a role in releasing force and reducing bumps.

[0049] In addition, in order to further improve the guiding effect of the partition assembly on the lithium battery, a guide member that can move along the length direction of the partition plate is also provided in this embodiment. Figure 7-8 As shown, two side grooves 15 are symmetrically opened on the left and right outer sides of the partition plate 14 along its own length direction, and a plurality of guide members 16 are slidably connected to the side grooves 15. The guide members 16 are coated on the outer surface of the partition plate 14, and there is a certain distance between adjacent guide members 16. The air avoidance treatment can reduce the contact between the lithium battery and the partition plate, reduce friction, avoid damage to the lithium battery, and reduce costs.

[0050] Specifically, Figure 9-10 As shown, the guide member 16 includes a bracket 161, the bottom of the bracket 161 is open to form a bracket slot 162 sleeved on the top of the partition plate 14, and the inner wall of the bracket slot 162 is symmetrically provided with two outwardly protruding limiting protrusions 163, and the limiting protrusions 163 are movably engaged in the side groove 15, so that the guide member 16 can slide relatively along the side groove 15. Two side frames 164 are symmetrically provided on the outer walls on the left and right sides of the bracket 161, and the side frames 164 are fixedly connected to the bracket 161. A mounting frame 165 is installed on the side of each side frame 164 opposite to the bracket 161, and a plurality of guide rollers 166 are rotatably connected to one side of the mounting frame 165, which are used to keep the battery cell accurately guided on the logistics line.

[0051] Embodiment 2

[0052] In another typical embodiment of the present application, a working method of the efficient conveying device for lithium battery helium detection based on the first embodiment is provided, comprising:

[0053] When conveying several lithium batteries of the same specifications, operate the separation components one by one on the conveying channel to slide along the connecting rod, adjust each sorting channel to have the same width and adapt to the specifications of the lithium batteries to be tested, and place the lithium batteries on each sorting channel;

[0054] When conveying several lithium batteries of different specifications, the separation components are operated one by one on the conveying channel to slide along the connecting rod, the sorting channel is adjusted to different widths according to the different specifications of the lithium batteries, and the lithium batteries are placed on different appropriate sorting channels according to the specifications.

[0055] The partition plates are slid along the connecting rods to adjust the intervals between adjacent partition plates, thus adjusting the width of the sorting channel. When transporting lithium batteries of the same specification, the lithium batteries are placed in different sorting channels of the same width, which not only realizes orderly transport of lithium batteries and facilitates detection, but also improves transport efficiency and detection efficiency.

[0056] When the specifications of the transported lithium batteries are different, the widths of the sorting channels can be different, or the same width can be set for several sorting channels according to the number of different specifications. This not only enables the simultaneous transport of lithium batteries of different specifications, greatly improving the detection efficiency, but also can adaptively adjust the number of sorting channels according to actual needs, thereby realizing the transport of lithium batteries of multiple specifications and large batches to meet the sealing detection needs.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
